'To all whom itniay co'ncemi Be it known that LWILLIAM E.-Wi1 m, a

citizen of'the United States of America, re-

siding at Toledo in the county of Lucas and have invented certain newand. useful Improvements in Car-Door the following is a speci-,.

State ;of Ohio,

Locks, of which fieation.

My invention relates to new and useful im rovements in car door lockingmeans, an .more paiticularly 'to looks that are adapted to support andretain the doors of a hoppercar in their closed position.

One of the ob'ects of the present invention-is to provi e'a lockingdevioethat is 1y simple in'constr'uction, readily assembl and readiiysecured to the car doors.

As is well known to those skilled in the art, the hoppers in a car areangularly disosed with relation to the car floor and the oors are swungfrom a point at the top of v the sides of the hopper.

The present invention contemplates a hook secured to the outside of thehopper while the lock comprises a body plate on which are a latch anddog, the late being secured to the lower end of the oor and at the sidethereof. Although onl one hook and one'lock are shown in the rawings, itwill of course, be understoodthat a similar hook and the cooperatinglatch will be supplied for the other side of the hopper and door so thatthe door will be sustained and locked from its opposite outer corners.With these and otherobjects in view, the

- invention consists in certain new and novel arrangementsand'combinations of the ock secured to thea-bottom of'the "door. x

will be hereinafter morefully descri d and Fig. 3 isan elevationallooking at right les to the .plane. of 'the .door, showcheap tomanufacture and easilyouter side of the plane below that of the outeredge of the Inge arts as now to the drawings showing a' cor 'tion untilthe dog 14 is swung rearwardl Referring now to the several figures, a

a hopper is own together with an outer flange 2 on a hopper door 3.

The hi pgint of the door 3 is not shown, but it understood that it is ata point near the tap of'the hopper. Securely riveted to'the 51 e of thehopper is'a casting 4 having its lower end formed in the shape of thehook 5 which extends beyond the outer edge of the hopper plate andbeyond the flange 2 of the door 3. This hook 5 has the. supporting 6formed thereon in parallel relation l die wit the outer free edge of thehopper side plate 1 and theplane of the door 3.

'Securely riveted to the bottom" of the the triangular bracket plate "7provided with the inte a1 bosses or posts 8, 9 and 10 fragmentaryportion 1 of the side plate of which exten beyond the o posite sides ofi rest on the bottomof t e door 3 and throu h which the rivets 12 arepassedso that t e plate 7 will extend in a 2. The ortions ofthe bosses 8and 10 which exten from the opposite side of the plate 7 form pivotalbearings extending normal to the lane ofthedoor for the rece tion of apivotal latch 13 and a dog 14 a apted toswrn parallel tosaid door. Thelower boss 9 it t 19 side of the plate and the upper boss 8 have a strapriveted-to them' to retainthe dog. 14 and hold the latch 13 ed as at 11for from lateral movement, while the downward movement of the latch 13will be limited by the boss 9 as may be clearly seen in Fig. 3. Thelocation 0 the casting 4 with relation to the plate 7 is such that whenthe door is clcped and the latch 13 is in its locked position, asshown=in the j'difl'erent figures, said latch will rest on the ledge cannotbe lifted or removed from this posiwhich may be done by striking theoutwar ly extending lug- 16 of the dog with-a hammer or otherinstrument. g V The casting 4'as well as the plate 7 and latch 13 may besli htly cored or ribbed as 60f the hook and I ios shownin the severefigures to provide 813- flcient strength' for these members, ae'these 1odoor 3 and directly behind the flange 2--is locking devices,as a whole,must be relatively I strong, since the doors and the load are comparatvely heavy. g

The shape of the lower outeredge of the hook 5 is such that it willraise the latch asthe door is swun to its closed position so that thelatch wil drop into place on the ledge when the door is in its final orclosed SOSltiOIl. In other words, the latch will re in place on theclosing of'the door and wil there be further securely held in place bythe jamming of the dog into position.

When the do or cam 14 is forced to locked position t e resulting wedgingaction ofthis arti'between the latch 13 and the bracket upon which thedog is pivotally mounted communicates, an upward thrust to said bracketand to the door upon which the latter is secured, thereby causing thedoor 3 to be supported and maintained against 'saging and shifting onits hinges endwise of t e door. The fixed hooks 5 which are se- I p doormay be provided with the outwardly cured .to the opposite sides of thehoper overlap the side edges of the door an co- 0 erate therewithto'prevent any substantial sidewise movement of the door when the latteris in closed position. .It will heappreciated that the disadvantagesincident to shifting movements of the doors when the car is in serviceare substantiallyeliminated in a structure embodying my invention.

' From theforegoing it will be seen that the extending flange 2 whichwill strengthen the door and also shelter the bosses or posts on theplate 7 from injury, while at the same time the flange does not ofierany obstruc tion to the locking device as these bosses are of suflicientlength tohold the lock be yond the lower edge of the flange.

It will also'beseen that I have provided alock which is extremelysimple, that will dro into-place when the door is closed and "understoodthat the device -might well be on t e other hand cannot becomeaccidental-. 1y disenga ed inuse.

Althoug I have shownthe locking device in conjunction with ahopper door,it willbe used with drop bottomdoors on cars of other" so ty es ila nyslight changes may be made with- I out inanyway departing froin'thespirit and scope ofthe invention.
